In an attempt to start partitioning of an AlphaServer, in order to install Gentoo Linux on a second partition, I got into trouble with FDISK v2.12r
Now ABOOT does not recognise a valid partition table anymore. Removing the OpenVMS partition would not be a problem, but I want ultimately both OpenVMS and Gentoo to coexist.

The original partition table was made using OpenVMS, and FDISK was showing the following information prior to start:

Luckily, I had the data regarding the placement of the partitions. This is very recommandable to keep the new partition scheme consistant with the scraped partition table. This waz, I did not even loose any data. Great!

So, now I have my BSD partition table back.

Any idea what is this bootstrap command i with FDISK ?
This special modes are not documented in the man pages, and not clarified in the Gentoo Handbook.
Somebody has a clue, is this a replacement for SWRITEBOOT and ABOOTCONF ?
